Object a has a mass of 20 g

The value of 1.0004 to the power 1 by 2 using Binomial approximation is

IgorLugansk [536]

Given:

The given value is $(1.0004)^{\frac{1}{2}}$ .

To find:

The value of the given expression by using the Binomial approximation.

Explanation:

We have,

$(1.0004)^{\frac{1}{2}}$

It can be written as:

$(1.0004)^{\frac{1}{2}}=(1+0.0004)^{\frac{1}{2}}$

$(1.0004)^{\frac{1}{2}}=1+\dfrac{1}{2}\times 0.0004$ $[\because (1+x)^n=1+nx]$

$(1.0004)^{\frac{1}{2}}=1+0.0002$

$(1.0004)^{\frac{1}{2}}=1.0002$

Therefore, the approximate value of the given expression is 1.0002.

Calcular la energía cinética de un cometa cuya masa es de 5×10 elevado a 31 kg y se mueve con velocidad de 216000km/h

PolarNik [594]

The kinetic energy is $9\cdot 10^{40}J$ .

Explanation:

The kinetic energy of an object is given by

$K=\frac{1}{2}mv^2$

where

K is the kinetic energy of the object

m is the mass of the object

v is the speed of the object

For the comet in this problem, we have:

$m=5\cdot 10^{31} kg$ is its mass

$v=216,000 km/h$ is the speed

First, we convert the speed from km/h to m/s:

$v=216,000 \frac{km}{h} \cdot \frac{1000 m/km}{3600 s/h}=60,000 m/s$

Therefore, the kinetic energy of the comet is

$K=\frac{1}{2}(5\cdot 10^{31})(60,000)^2=9\cdot 10^{40}J$

What happens when the crests of two waves overlap

Sergio [31]

There are two main types of wave interference: constructive interference and destructive interference. Constructive interference happens when the amplitude of the combined waves is larger than the amplitudes of the single waves. This can occur when the crests of two transverse waves overlap.

Hope this helps!!! :D

A bolt of lightning discharges 9.7 C in 8.9 x 10^-5 s. What is the average current during the discharge?

Anastaziya [24]

Answer: $1.089\times 10^5\ A$

Explanation:

Given

Charge discharged $Q=9.7\C$

time taken $t=8.9\times 10^{-5}\ s$

Current is given as rate of change of discharge i.e.

$\Rightarrow I=\dfrac{Q}{t}\\\\\Rightarrow I=\dfrac{9.7}{8.9\times 10^{-5}}\\\\\Rightarrow I=1.089\times 10^5\ A$

Therefore, the average current is $1.089\times 10^5\ A$

3. Will a plant grow higher with more light?

sleet_krkn [62]

Answer:

When we analyze the sentence we see that this is a hypotype with the growth of plants must behave and it has a prediction included.

Therefore the correct answer is a

Explanation:

In this exercise you are asked to identify the given sentence with a specific part of the scientific method.

Among the parts of the method we have.

* Independent variable . The controlled variable in research

*Dependent variable. The magnitude measured in the experiment

* Control variable. The magnitude that is not controlled

*Experiment. It is the design of the procedure to evaluate the hypothesis

* Hypothesis. It is the assumption with which scientific work begins

* Prediction. It is a consequence of work if the mortgage is correct.

When we analyze the sentence we see that this is a hypotype with the growth of plants must behave and it has a prediction included.

Therefore the correct answer is a
